packet.link.vlan - VLAN module

DESCRIPTION

Decode Virtual LAN IEEE 802.1Q/802.1ad layer

CLASSES

class VLAN(baseobj.BaseObj)

VLAN object
Usage:


    from packet.link.vlan import VLAN


    x = VLAN(pktt)
Object definition:
VLAN(


    pcp   = int,  # Priority Point Code


    dei   = int,  # Drop Eligible Indicator


    vid   = int,  # VLAN Identifier


    etype = int,  # Payload Type


    psize = int,  # Payload Data Size
)

Methods defined here:
---------------------
__init__(self, pktt)
Constructor
Initialize object's private data.

Packet trace object (packet.pktt.Pktt) so this layer has
access to the parent layers.
__str__(self)
String representation of object
The representation depends on the verbose level set by debug_repr().
If set to 0 the generic object representation is returned.
If set to 1 the representation of the object is condensed:


    '802.1Q VLAN pcp: 4, dei: 0, vid: 2704 '
If set to 2 the representation of the object also includes the type
of payload:


    '802.1Q Virtual LAN, pcp: 4, dei: 0, vid: 2704, etype: 0x0800(IPv4)'

FUNCTIONS

vlan_layers(pktt)
Get all nested (stacked VLANs or QinQ) VLAN layers
A Packet layer attribute is created for each VLAN layer:
vlan1, vlan2, ..., and vlan. The last packet attribute
is always vlan.
